ANCHOR YOKE FOR NON-SKID CHAINS.

APPLICATION FILED APR. 9, I920.

Patented Feb. 1,1921.

Inventor NNITED TA t TE T OFFICE Y To all whom it may concern L a 1 Beit known that I, WILLIAM N. SLE cHEn, a citizen of the United States,resid1n at Troy, in the county of R'ensselaer and. tate ,oi New York,have inventednew and useful Improvements "in Anchor-Yokes for Non-SkidChains, of which the following is a s ecification.

eference may be had to the accompany .ing drawings, and the referencecharacters marked thereon, which form a part ofthis specification.Similar characters refer to similar parts in the several figurestherein.

This invention relates to the type of nonskid devices employing shortcross-chains connected at their ends with anchor-yokes mounted upon aconvenient portion of the wheel.

The principal object of the invention is to provide an anchorage for theend-links of the cross-chains to which said links can be readilyattached and from which they can be readily intentionally detached, butfrom which their accidental detachment is practically impossible.

Other objects will appear in connection with the following description.

Figure 1 of the drawings is a view in cross-section of the telly of awheel with a tire mounted thereupbn showing in elevation a cross-chainsecured to the Wheel by means of my improved anchor-yoke applied to aspoke of the wheel.

Fig. 2 is a view in perspective of the anchor-yoke detached,illustrating the manner in which the anchoring links of the crosschainare applied to the anchor-posts on the yoke.

Fig. 3 is a plan view of the a11chor-yoke.

Referring to the drawings wherein the invention is shown in preferredform, 1 is the telly, 2 is a spoke, 3 is the rim, and lthe shoe of thetire of an automobile wheel.

My improved anchor-yoke is preferably made in two parts, 5 and 6, ofgeneral. semicircular form. adapted to embrace between them one of thespokes, 2, of the wheel and to be clamped thereupon by means of screwbolts, 7, connecting together ears, 8, on the member, 5, with respectiveears, 9, on the These anchor-posts extend inwardly on opposite sides ofthe spokes, 2, and each is formed WlthtWO transversely elongated en Eachofthese anchor-posts is adapted to. recelve a llllk, 11*, which can beapplied to the posts by first bringing the longltudinal axis of thelinkparallel with the longitudi nal axis of the outermost enlargement, 12,in

which position the link can be passed over the enlargement, 12, and thenswinging the link around the post until the longitudinal axis of thelink is parallel with the longitudinal axis of the enlargement, 13, inwhich position the link can be passed over said enlargement, 13.

When the chain, 11, and the end-links, 11, assume their normal positionsafter the endlinks have been thus mounted upon the anchor-posts, 10, thechain will be securely retained upon the wheel until intentionallyremoved by disconnecting the end-links, 11, from the anchor-post by areversal of the several movements by which said'links were applied tothe anchor-posts. The positions which the end-links are required to takein passing over the respective enlargements, 12 and 13, are unnaturalpositions in the operation of the chain in use upon the runnin vehicle,so that accidental escape of the links,

11, from the anchor-posts is practically impossible.

The device is rendered even more efiective by employing chains withtwisted links as shown, as twisted links must be more accuratelypositioned in passing over the enlargements in planes oblique to theaxis of the yoke.

For certain purposes of the invention however, chains having ordinaryplain links may be employed, and the enlargements on the anchor-postsmay be in any desired plane generally transverse with respect to theanchor-posts.

By the use of my invention very. slack cross-chains may be emplo edwithout danger of their becoming acci entally detached from theanchor-posts, the use of slack chains being desirable in devices of thiskind, because the chain is thereby permitted p ofthe yoke as shown in F1g. 1, and their longitudinal axes j.-"- PatentedyFeb. 1,1921.Application meanjrn 9, 1920.

freedom to position between the tire and the road-bed instead of beingheld to a a substantially definite pointon the shoe at all times. -VVitha slack chain the wear is dis tributed over a greater area of the tirethan i with a tightly fittingchain.

' Vlfli'at l cl-ainr as new-and desire to secure by Letters Patent is 1.An anchor-yoke for non-skid chains, hayinga chain-linkren-gaging postformed with: two transversely elongated enlarge-- nlentsat differentdistances from. its base i with their longitudinalaxes at anaangle toeach other.

2. Ananchor-yoke for non-skid chains, having a chain-link-engaging postformed Wli3h; -tW0 enlargements at different distances "--,fromits-base, said enlargements being in planes oblique t0 the axis of theyoke and elongated; one in a direction at an angle to the other. I

3. The combination with a non-skid chain; of an anchor-yoke formed withtwo transversely elongatedenlargements at dif- -ferent distances fromits base, one adapted to receive a link of the chain in one position ofsaid link, and the other to receive said link when swung around the postto another position.

4. The combination with a non-skid chain having twisted links; of ananchor-yoke formed with two enlargements at different distances from itsbase, said enlargements being in planes oblique to the axis of the post,and elongated, one in a direction at an angle to the other, requiring atwisted link of said chain to be presented in different angularpositions to pass the respective enlargements.

In testimony whereof, I have hereunto set my hand this 6th day of A ril,1920.

WILLIAM SLEICHER.
